One would hope that famous landmarks (Empire State building, WTC,
Statue of Liberty, etc....) have their locations purposely fudged to avoid
being targeted by terrorists using buzz-bomg/gps combos.

Also, the WTC observation deck moves significantly in the wind.
Just go to the bathroom or run a water fountain and watch the water move
back and forth.
